Closing command prompt from JAVA

Hi,

Many times developer ask question how to close command prompt after
launching the application?
or
How to exit from batch file after execution.

Here is all possible ways to do so.
1. Use javaw.exe for launching your application and exit.
2. Create an executable jar file so that just double clicks for launch.
3. Create exe from jar files.

If you want to exit from command prompt after calling your exe file.
Then apply the same concept which we are using for tracing output
from exe.(see previous post)

Technique:-
1. You have to insert a line on your code which print "Loaded" on output.
2. Crate a jar file then exe from jar file.
3. Again make a java file for launching your exe file.
4. Get the InputStreamReader from your process.
5. Check for string "Loaded" on output.
6. If you get "Loaded" then exit.

See the full source code.

class Loader

{

    public static void main(String as[])

    {

        try

        {

            System.out.println("Loading application.........");

             //pass the name of your exe in place of my.exe

             Process p = Runtime.getRuntime().exec("my.exe");

             //getting inputstream reader from process

             BufferedReader reader = new BufferedReader

                                     (newInputStreamReader(p.getInputStream()));

             String line = reader.readLine();

              //exit from this class when get "Loaded" from your application

              while (line.equals("Loaded") == false)

               {

                       line = reader.readLine();

               }

                reader.close();

            }

            catch (Exception e)

            {

            }

    }

}
call exe from a batch file like...
java Loader
